board: xilinx: zynqmp: Register alternate FPGA device for zu63dr_SE
The zu63dr_SE and zu67dr_SE devices share the same silicon ID code
0x046D7093 and cannot be distinguished at runtime. The SOC driver
reports zu67dr_SE for this ID, which causes fpga loadb to reject
zu63dr_SE bitstreams.
Register zu63dr_SE as an alternate FPGA device when zu67dr_SE is
detected. This allows users to load either bitstream by selecting
the appropriate device number:
- Device 0 (zu67dr_SE): fpga loadb 0 ${loadaddr} ${filesize}
- Device 1 (zu63dr_SE): fpga loadb 1 ${loadaddr} ${filesize}
